Claims.

This invention relates to a collapsible music holding attachment for guitars.

Hitherto music-holding attachments for guitars have been devised which when in their attached .position have somewhat impaired the tone of the instrument. It is among the objects of the present invention to overcome this defect by providing, to support the device upon the guitar, a clamping means which will overlie less of the resonant wall portion of the guitar and will be applied thereto in such a manner as not to impair the resonance thereof, and also will not interfere with the players manipulation of thestrings of the instrument.

Among other objects of the invention are to provide a lighter and more compact device of the stated kind and one particularly well adapted for being attached to a Hawaiian guitar; to provide the device with a music rack which the player, whether a pupil or a member of an orchestra, may use to support the music in a safer more stable manner with less danger of the music stand becoming displaced and discharging the sheet music supported thereby; to provide a device with no parts apt to get out of order, usable for a long period of time, and capable of being manufactured at a lower cost.

An additional object is to provide an assembly of base, music-holding rack and clamp wherein the rack, which is of a skeleton, foldable character, may be compactly nested in its folded condition against the upper side of the base, while the clamp is arranged to swing up against the lower side of the base, when the attachment has been removed from the guitar.

Other objects, advantages and features of invention will hereinafter appear.

Referring to the accompanying drawing, which illustrates a preferred embodiment of the invention,

Fig. l is 2, perspective view of the device, the upper portion of a guitar upon which it is mounted being included in the view. In this view dotted lines indicate the manner in which the music rack is folded, and also the folded position of the clamp.

Fig. 2 is a section on line 2-2 of Fig. 1, a portion of the guitar being shown in dotted lines.

Fig. 3 is a perspective, on a smaller scale than the other views showin a corn lete Hawaiian i g 1 guitar with the device applied thereto, dotted lines indicating the operative position of the music rack, and full lines showing said rack partly outswung.

Referring in detail to the drawing, a base is provided consisting of an elongated, substantially rectangular plate 5 having along its front side edge a right angularly upstanding flange 6 and along its rear side edge anupstanding flange 1 deflected somewhat toward the rear, The latter 2 flange has near one end an inwardly or forwardly projecting pivot stud 8 and near its opposite end a like inwardly projecting pivot stud 9. A strap metal arm III has one of its end portions overlying the inner face of said flange 9 being pivotally attached to said flange by said stud )8, while a second like arm- H has one of its end portions bifurcated at l2 for straddling the stud 9 thus being swingably related to the stud Sin an un seatable or removable manner. A bar l3 bridges the space between the outer ends of said arms l0 and H and is pivotally connected with each of said arms, thus cooperating with them to form a music holding extension for the base 5, to fold which it is only necessary for the musician to use one hand, with which he will grasp and unseat the arm I i and will thereupon fold up the three arms IE), I! and it in the manner indicated by dotted lines in Fig. 1.

The clam-p for attaching the device to the guitar [5 comprises an L-shaped bar It having a longer arm 11, and having its shorter arm i8 transversely underlying the entire width of the midlength portion of the base 5 and turnably connected thereto by reason of being interposed be tween an upper bearing plate l9 and a lower bearing plate 2G, both of said bearing plates being shown secured to the base by rivets 2|. By this arrangement said L-shaped bar is so mounted that its longer arm H can swing to and from an underlying relation to either end portion of the base 5, or can be positioned in a right angularly pendant relation thereto.

An elongated strap metal loop 25 is attached to the aforesaid swingable arm ll, said loop having twin side runs 26 which extend 'adjacently along each side of the arm I! of the bar 5, this loop having apertured end runs 21 and 28 forming bearings through which the arm I! passes so that the loop is turnable upon the arm, A clamp jaw 29 overlies and is secured to the outer end run 28of said loop, said jaw having at one side of the loop a heel portion 39 which forms a finger-hold for manual retraction of the clamp against the opposition of a spiral compression spring 3 l coiled loosely around the arm ll of the clamp. The lower end of said spring abuts against an annular shoulder 32 resulting from the tubular abutment 33 mounted upon said arm ll in a surrounding relation th reto, the upper end of said spring abutting against the lower face of theiruh 27 of the loop to urge the jaw 29 toward its-gripping position, wherein it underlies the guitar l5 and presses its padded portion 35 thereagainst, the opposite side of the guitar abutting against twin pads 35 attached to the lower face of the end portions of the base 5. The lower end of .the diametrical enlargement 33 abuts against the upper face of said jaw 2%! whenever the jaw is allowed to be moved inwardly by the spring a little distance beyond that necessary for gripping the guitar which the device is designed to grip, hence it is only necessary manually to retract the clamp jaw a short distance preparatory to applying it to the guitar. A finger (or thumb) abutment piece 39 carried by the projecting arm extremity 3:"! aids the operator in single hand retraction of the jaw.

I claim:

1. In a device of the kind described, a base consisting of an elongated, substantially rectangular plate of rigid sheet material having'an upwardly directed flange extending along each of its side edges, one of said flangesbeing a mounting flange, a first arm pivotally attached permanently to the inner side of one end portion of said moun ing flange so as to swing in approximately the same plane as that in which said mounting flange extends, a second arm having one of its end portions removably connected to the inner side of that end portion of said mounting flange which is opposite to the first recited end portion thereof, and a bar bridging the space between the outer ends of both of said arms and permanently pivoted to both of them, said arms and bar forming for said base a three-member extension wherein, when said second arm is removed from said base, all three members of said extension are foldable alongside of each other and are then nestable between the flanges of said base, and means detachably to secure said base to a guitar.
